Referring tothe drawings in a more particular description it will be seen that thisbarrel comprises an inner metal receptacle III in the form of a slightlytapering barrel and made from two pot-shaped halves H and I2substantially similar in construction and an outer metal casing l3 alsoformed of two substantially similar halves l4 and I5. v 50 Thereceptacle halves H and I! are preferably each formed integrally from asingle piece of sheet metal of the proper sort. size and thickness andshaped as by stamping or pressing so Application March 7, 1934, SerialNo. 714,439

permanently and readily joined together as by to be larger at the centerof the barrel and with the free or joint edgeof the side wall l6provided with an outwardly extending flange I'I. Preferably the heads orends I! of the receptacle halves join or merge with the adjacent smallerends of the walls 16 with a, rounded or curving junction 19. This curvedJunction I9 makes the receptacle better adapted to be kept clean throughavoiding a sharp angle on the inside of the barrel and also is thebetter practice in the 10 metal working of drawn or stamped metal andalso gives a wide, rounded or curved surface to be engaged on theoutside of the receptacle by the inner surface of the casing ashereinafter described. The ends or heads 18 of the recep-V tacle halvesII and I! are conveniently formed alike even as to having'both headsprovided with a depression 20 adapted to receive the inner end extendsso as to entirely empty the barrel. The

integral flanges ll extending outwardly from the free edges or largerends of the receptacle halves II annd l2 extend outwardly in a plane atright angles to the longitudinal axis of the barrel so that when tworeceptacle halves are brought together the opposing faces of the twoflanges or at least a considerable portion of the said opposing faceswill flt closely and smoothly together and adapt the two halves of thereceptacle to be It will be understood of course that the two halves andparticularly the entire circumference ofthe opposing meeting edges ofthe two flanges will be pressed together closely enough to form not onlya good mechanical jointybut also a liquid-tight and air-tight joint. Theparts at this stage of manufacture are represented by the detailsectional view Fig. 3. I

Preferably the outer or non-engaging surface 22 of each flange ll ofthe'receptacle halves will be provided with a recess 23 reachingentirely around the receptacle except where interrupted by the insertionof the bung piece 24. 'rms'ao recess 23 is conveniently and preferablyformed by making each flange H with a roughly semicircular or curved rib25 proiectinsgaway from the engaging surface of the flange or in otherwords, projecting out from the outer or non-en- 56 will be outside therib another zone as 21 where an appreciable width of the flanges cometogether closely and may be welded at the same time the zone 26 iswelded or at a later time as desired. The recesses 23 open outwardly ona slant away from the barrel but with each recess facing towards thehead of its half of the recep tacle. This is for a purpose that wil lbe'-explained hereinafter.

The outer casing l3 as already suggested has its halves l4 and it formedof sheet metal and preferably these casing halves are each formed from asingle piece of sheet metal suitably formed as by stamping or pressing.The casing I3 is more distinctly barrel-shaped in form, that is, itbulges outwardly more at its center than does the receptacle 59.. Eachcasing half is formed so as to have a side wall proper 28, an end orhead 29 and connecting these parts a chime ance to a wooden barrel.

30 which is U-shaped or loop-shaped when seen in transverse section ateither edge of the barrel.

The side walls proper 28 of each half of the casing are shaped adjacent,their smaller ends with a curve or rounded concave face-3l on the insideto closely fit the rounding zone or round- 7 ing junction I9 on theoutside of the receptacle.

From this zone where the outer casing closely engages the junction faintof the side walls and ends of the inner re eptacle, the side wall 28 ofthe outer casing sl nts away from the side wall- IB of the innerreceptacle as it extends towards the larger or central part of thebarrel and these parts remain so spaced apart for the balance of thelength of both side walls. Preferably, however, this slanting of thewall 28 of the casing is not regular, but is irregular in that there isa decided outward projection or protuberance as at 32 a little waystowards the center of the barrel from the engaging zone formed betweenthe rounded surfaces l9 and 3!. The part 32 preferably has an inwardlyextending reenforcing, bead 32a. Beyond this raised part or protuberance32 the wall 28 is reduced relatively for a zone as at 33 and then thereis another raised or enlarged zone'3l after which is a smaller nar-.rower zone 35. The raised zones 32, and 34 correspond roughly .to theprojections of the metal hoops upon the wooden staves of a woodenbarreland render the metal barrel similar in appear- These raised zones formintervening shoulders or steps in the casing side which tend tostrengthen the casing of the metal barrel andprevent its being pressedor forced inwardly in hard usage. These projections also aid in thehandling of the barrels and particularly in the handling or moving ofthe barrels in factories or for instance in breweries where the racksand runways are already shaped Y to fit the common wooden barrels havingmetal hoops. Preferably the extreme free edge of each side wall 29 isturned or slanted inwardly somewhat as at 36 so that when a casing halfis placed in position uponits end of a receptacle the edge of thisinturned band 36 will enter and preferably engage the bottom of therecess 23 already mentioned as being formed in the outer or back side ofeach flange II of the inner receptacle halves-1 1 When two oppositecasing halves have thus been placed in proper position against theopposite parts of a receptacle, the parts will be in the position shownin the enlarged sectional view Fig. 4 with an inturned band 36 of .eachof the two casing halves entering and preferably engaging the oppositelylocated recesses 23 of the already assembled receptacle.

With these parts securely held in position a welding operation,preferably an arc welding operation, is carried out so as to form astrong, heavy weld uniting the opposing bands 36 of the outer casinghalves to the adjacent flanges of the receptacle and also more securelyuniting the outer parts of the said twoflanges ll of the two halvesofthe receptacle even if those outer parts have theretofore been unitedby the preliminary welding process used to initially join the two partsof the receptacle. Fig. 5 shows thefcondition of these parts after sucha welding operation has been carried out and particularly shows that thematerial added during such welding operation and the heating of theadjacent parts of the barrel have made a homogeneous joint between theouter parts of the two flanges of the inner receptacle and also betweenthe adjacent parts of the two halves of the outer casing.

It will be seen that this central joint between the two parts of thereceptacle and the two parts of the casing joins all these four-partstogether and so the center of the inner, receptacle is braced and heldin spaced and concentric relation relative to' the outer casing by thetwo flanges ll of the receptacle projecting out to and substantiallyinto line with the outer wall of the outer casing and permanently weldedthereto.

. The chime 39 already mentioned as connecting the smaller end of eacheach casing side wall 28 and its head or end 29 is formed by the metalbeing shaped beyond the interengaging zones 3| and E9 of the barrel tohave a zone 39 projecting lengthwise of the barrel for an appreciabledistance and then turned inwardly for a less distance forming a ring 49upon which the barrel stand when on end and thereafter the metal isturned back towards the inside of the barrel forming a zone as Alextending towards but not reaching the head' or end I8 of thereceptacle.

.The zone preferably slants outwardly about entirely around each end ofthe barrel. If de-' sired this may be further re-inforced by a ringpreferably of angle-shaped metal 42 placed in the bottom of the chimeand securely fastened in place against the ring 49 and against the outerwall 39 of the chime by suitable welding.

It will be understood that each half as and I2 of the receptacle will beprovided with a semiturned edges to be suitably fastened as by weldingto said sleeve member 2|.

Preferably the bilge or bulging part of the outer casing is furtherreinforced by each half of the outer casing having a specially formedchannelshaped ring of metal 44 provided and secured to the inside of thesaid casing half preferably within the zone 34. This reinforcing ringhas its loop or connecting portion 45 towards but spaced from the innerreceptacle and its two legs 43, preferablyslant somewhat away from eachother as they extend toward the outer casing and at their outer ends thelegs 48 are provided with oppositely turned feet 41 substantiallyparallel to the loop portion 45 and resting flat against and securelyfastened to the said casing as by welding. It will be seen that theserings of channel-shaped metal with their braced and securely fastenedlegs will.

said encircling main joint of said main parts from any injury ordistortion that might result in breaking the tightness'of said joint. Itwill be understood too that these reinforcing channelspaced rings 44 areplaced and secured within the casing halves before the casing halves aremounted upon the inner receptacle and accordingly it will be seen thatthese reinforcing rings can be very securely welded or otherwisefastened in place to the casing halves inasmuch as access is at thattime readily had to both the inside and outside of the casing halves.

Preferably a packing 43 as of some strong but slightly resilient andheat-insulating material is interposed between the central parts of thehead of the casing 23 and the 'end or head ll of the inner receptacle atboth ends of the barrel. This allows the great strength of the outercasing head and chime to be utilized to brace the thinner head of theinner receptacle from any bulging or distortion such as might be causedby dropping the barrel endwise when filled. The packing being slightlyresilient and heat-insulating gives a sufficient contact between thesetwo parts without interfering with the heat-insulation maintainedthroughout practically all of the rest of the barrel due to the dead airspace existing between the outer casing and the receptacle.

It willbe noted that when the barrel is rolled or moved flatwise on thelargest part of its bilge the contact with the floor will be against thelargest zones 34-34 spaced away from the central joint of the barrel.This operates to relieve the said central joint from direct engagement 1with the floor or with obstructions upon the floor and also operates tominimize the conduction of heat through said'joint to the floor as wouldhappen if the joint itself rested upon the floor.

It will be seen that the inner receptacle is supalso brace thereceptacle within the casing and is well adapted to take a large part ofthe side strain and also of any end strain that may be placed upon thebarrel.

On account of the extent by which the chime 33 extends beyond the sidesand head of the barrel and on account of the outer projection of thezones 32, direct contact of the casing with the ground or floor cannotbe had at the casing opposite the zone 3!. This is illustrated by thestraight line placed in the lower left hand part ofFig. 1 and extendingpast the zone 32 and the chil'ne 30. Incase the barrel were placed ordropped against the floor at the angle represented by said figure andsaid straight line 49-49, it will be seen that the strain of contactwould not be taken directly against thezone 3|, but would be'taken bythe raised zone 32 and the chime 3|.

The central aperture ill of the tap bushing 2| tapers to be slightlysmaller as it proceeds inwardly to fit the usual tapering tap bushingplug which is ordinarily of wood. In order however to hold said plugmore securely against accidental displacement I provide about midway thedepth of the aperture II a groove II cut back into the wall of thebushing. The outer part of this grove recedes sharply back into thebushing forming a shoulder 32 the outer part of which is sub-'stantially at right angles to the adjacent or outer part of the wall ofthe aperture 50. The inner-part of this groove then slants or curvesgently back towards the line of the inner half 'of the wall of thebushing so as to smoothly merge as at I3 with the said inner half of thewall of the main aperture. In other words this groove as will appearparticularly from Fig. 7 is in the shape roughly of a half of aconventional heart-shaped figure with the decided shoulder 52 at theouter edge of the groove and the smooth merging zone 3 at the inner partof the groove. 'It will be seen that then as a regular tapering tap plugIi is forced into this tap bushing the inner half of the plug willpassthe slanting or rounding zone I3 without being burred outwardpart ofthe plug II in Fig. 'I) and act as a lock to prevent accidental orpremature displacement of the plug. when it is desired however toremovethe plug sufllclent power applied in the usual way to the plug by aproper device will I accomplish the purpose.

The bung-piece or bushing 24-has its central tapering aperture 54provided with a similar reentering groove II having a relatively sharpshoulder 33 at its outer sideand a merging, slanting or curved zone I]returning to the regular slant of the inner part of the main apertureall for a similar purpose and operating in the same way-to retain thebung against premature or aocidental displacement. vReferring again tothe detailed sectional view Fig. '7 of the tap bushing outer wall is.The close engagement oi! the flange against the undercut wall 59especially when the parts are welded operates to strengthen the jointhere made against loosening these parts when strain is placed upon thebushing as by the driving in 01' the tap bushing plug.

similarly the inturned halves of flanges ll semi-circular on each halfoi the outer casing fit closely underneath the undercut peripheral wall62 of the bung piece or bung bushing 24 and when the two halves of theouter casing are welded in place at the main central circumferentialjoint these inturned flanges 43 make a very rigid support for the saidbungipiece against any strain tending to force the bung piece inwardly.

Such inward strain is sometimes placed upon the Letters Patent is:
